Probably it is nothing besides a new car vs old car...... How many miles did your 2011 had?

On a second note, it still have no idea why anyone would trade in a 2011 for a 2013?

+1 I too cant seem to understand this. Unless one really hated the options/color combo on the previous car, OR you were switching transmission. I personally think its a waste of money but thats just my opinio...live and let live
